This is a narrowband image with H-a, OIII, and SII data (although there is very little OIII present). About 8 hours all together. AP Starfire 142 on AP Mach1 mount, QSI 583wsg camera. I wasn't happy with any of the usual color mappings, so this is an odd combination: Red is H-a, blue is SII, and green is a highly processed blend of H-a and OIII. Then the whole thing was hue shifted. Hey, I do whatever it takes to get the image I want!
